A display device includes a first substrate and a second substrate. The first substrate includes a first base substrate, a drive layer, and an optical layer, and is divided into a display area, and a non-display area. A first connection pad and a second connection pad are disposed in the non-display area. The second substrate is disposed facing the first substrate, and includes: a second base substrate including a sensing area, and a non-sensing area; and a touch sensor disposed on the second base substrate. The touch sensor includes a touch sensing electrode, a touch pad, and a sensing line electrically coupling the touch sensing electrode with the touch pad. The non-display area of the first substrate is bent so that the first connection pad is electrically coupled with the second connection pad, and the second connection pad is electrically coupled with the touch pad.

4. The display device according to claim 3 , further comprising: a first conductive ball between the third pattern and the touch pad.
5. The display device according to claim 4 , further comprising: a second conductive ball between the first pattern and the first connection pad.
6. The display device according to claim 4 , wherein the first pattern and the first connection pad directly contact each other.
7. The display device according to claim 3 , further comprising: a first conductive ball between the first pattern and the first connection pad.
8. The display device according to claim 7 , wherein the third pattern and the touch pad directly contact each other.
9. The display device according to claim 3 , further comprising: a conductive adhesive layer between the first pattern and the first connection pad.
10. The display device according to claim 3 , further comprising: a conductive adhesive layer between the third pattern and the touch pad.
11. The display device according to claim 2 , wherein the second connection pad comprises: a first pattern having a shape extending from the first connection pad; a second pattern in a through hole passing through the first base plate, and coupled with the first pattern; and a third pattern on a surface of the first base substrate that is opposite to a surface thereof on which the first pattern is located, the third pattern being coupled with the second pattern.
12. The display device according to claim 11 , wherein the first pattern faces the first connection pad, and wherein the third pattern faces the touch pad.
13. The display device according to claim 12 , further comprising: an elastic member between the first pattern and the first connection pad, and configured to maintain a bent shape of the first substrate.
14. The display device according to claim 13 , further comprising: a conductive ball between the third pattern and the touch pad.
15. The display device according to claim 13 , further comprising: a conductive adhesive layer between the third pattern and the touch pad.
16. The display device according to claim 2 , wherein the touch sensor further comprises: a second base substrate comprising a sensing area corresponding to the display area, and a non-sensing area corresponding to the non-display area; and a sensing line electrically coupling the touch sensing electrode with the touch pad, wherein the touch sensing electrode is on the sensing area, and wherein the touch pad is on the non-sensing area.
17. A display device comprising: a first substrate comprising: a base substrate comprising a display area and a non-display area, wherein the base substrate comprises at least one connection pad at the non-display area; a drive layer on the display area of the first substrate; an optical layer on the drive layer; and an encapsulating layer on the optical layer, wherein the non-display area of the first substrate is bent so that the at least one connection pad is indirectly electrically coupled with a touch pad of a touch sensor on a second substrate.
